Beschreibungdescription
Gehäuse für MotorsteuergeräteHousing for engine control units
Die Erfindung betrifft ein Gehäuse fü-er Motorsteuergeräte gemäß Anspruch 1.The invention relates to a housing for engine control units according to claim 1.
Bei den, aus dem Stand der Technik bekannten Halbleitermotorsteuergeräten (Sanftstartern) ist bekannt, eine Bypass- Funktion, das heißt eine Überbrückung eines Schalters über ein zusätzliches Schütz zu verwirklictxen. Die Schaltfunktionen der beiden Schalter müssen dabei von einer entsprechenden Ansteuerelektronik gesteuert werden. Insbesondere ist für die Ansteuerelektronik bei Motorsteuerger-äten mit einem größeren Leistungsumfang ein entsprechend größerer Platzbedarf für die Ansteuerelektronik vorzusehen. Dies kann dadurch realisiert werden, dass die Leistungsteileinheiten des Motorsteuergerätes in einem Basisgehäuse untergebracht sind und die Ansteuerelektronik in einem zusätzlichen eigenständigen Gehäuse.In the case of the semiconductor motor control devices (soft starters) known from the prior art, it is known to implement a bypass function, that is to say bypassing a switch via an additional contactor. The switching functions of the two switches must be controlled by appropriate control electronics. In particular, a correspondingly larger space requirement for the control electronics is to be provided for the control electronics in engine control units with a larger scope of performance. This can be achieved in that the power subunits of the engine control unit are accommodated in a basic housing and the control electronics in an additional independent housing.
Aufgabe der vorliegenden Erfindung ist es, ein Gehäuse für Motorsteuergeräte bereitzustellen, weHches flexibel an den Leistungsumfang des Motorsteuergerätes anpassbar ist.The object of the present invention is to provide a housing for engine control units, which can be flexibly adapted to the scope of the engine control unit.
Diese Aufgabe wird durch ein Gehäuse nach Anspruch 1 gelöst, indem an einer Seitenwand des Basisge-tnäuses eine Gehäuseerweiterung befestigt ist. Dadurch kann je nach Leistungsumfang das Basisgehäuse um eine entsprechend große Gehäuseerweiterung erweitert werden und so alle für das Motorsteuergerät notwendigen Bauteile in einem Gehäuse untergebracht werden.This object is achieved by a housing according to claim 1, in that a housing extension is attached to a side wall of the base housing. Depending on the scope of services, this allows the basic housing to be expanded by a correspondingly large housing extension and thus all the components required for the engine control unit can be accommodated in one housing.
Insbesondere kann die Gehäuseerweiterxing zur Aufnahme der Ansteuerelektronik dienen.In particular, the housing extension can serve to accommodate the control electronics.
Weitere vorteilhafte Ausführungen und bevorzugte Weiterbildungen der Erfindung sind den Unteransprüchen zu entnehmen. Die Erfindung sowie vorteilhafte Ausführungsbeispiele derselben werden im Weiteren anhand der nachfolgenden Figuren näher beschrieben. Es zeigen:Further advantageous designs and preferred developments of the invention can be found in the subclaims. The invention and advantageous exemplary embodiments thereof are described in more detail below with reference to the following figures. Show it:

Figur 1 zeigt ein dreipoliges Motorsteuergerät 1, mit einem Basisgehäuse 10, das in dem hier gezeigten Beispiel drei Leistungsteileinheiten 1* aufnimmt. Jede dieser Leistungsteileinheiten l1 realisiert dabei eine Bypass-Schaltfunktion. Die Oberseite des Basisgehäuses 10 ist mit einem entsprechen- den Deckel 30 abgeschlossen.FIG. 1 shows a three-pole engine control unit 1 with a base housing 10, which in the example shown here accommodates three power unit units 1 *. Each of these power unit units l 1 realizes a bypass switching function. The top of the base housing 10 is closed with a corresponding cover 30.
Erfindungsgemäß kann nun, wie in Figur 2 dargestellt, an einer Seitenwand des Basisgehäuses 10 die Gehäuseerweiterung 20 befestigt werden. Dazu sind, wie in Figur 1 gezeigt, an einer Seitenwand 10 λ des Basisgehäuses 10 entsprechende Öffnungen 11, 12, und 13 vorgesehen, in die entsprechende Befestigungsmittel der Gehäuseerweiterung 20 eingeführt werden können.According to the invention, as shown in FIG. 2, the housing extension 20 can now be attached to a side wall of the base housing 10. For this purpose, as shown in Figure 1, on a side wall 10 of the base housing 10 λ corresponding openings 11, 12, and 13 are provided, can be inserted into the corresponding attachment means of the housing extension 20th
In dem hier gezeigten Ausführungsbeispiel weist, wie in Figur 2 dargestellt, die Gehäuseerweiterung 20 als Befestigungsmittel im unteren Teil eine Hakenverbindung 21 sowie zwei Hammerköpfe 22 im oberen Teil auf. Zusätzlich sind zwei Sch-traubverbindungen 23 vorgesehen, mit denen die Gehäuseerweiterung 20 fest und damit unverlierbar mit dem Basisgehäuse 10 verschraubt werden kann.In the exemplary embodiment shown here, as shown in FIG. 2, the housing extension 20 has a hook connection 21 and fastening means in the lower part two hammer heads 22 in the upper part. In addition, two Sch-graub connections 23 are provided, with which the housing extension 20 can be screwed firmly and thus captively to the base housing 10.
In den Figuren 3-5 sind die einzelnen Montageschritte des Erweiterungsgehäuses 20 an das Basisgehäuse 10 dargestellt. So werden in dem in Figur 3 gezeigten ersten Schritt die Gehäu- seer eiterung 20 mit dem Basisgehäuse 10 verbunden, indem die Gehäuseerweiterung an der Seitenwand des Basisgehauses 10 in Pfeάlrichtung bewegt wird. Dazu muss aber zuerst die Haken- verloindung 21 in die entsprechende Öffnung 11 der Seitenwand 10' des Basisgehäuses 10 eingebracht werden. Beim Niederdrücken der Gehäuseerweiterung 20 in Pfeilrichtung hakt dann die Hakenverbindung 21 in der Öffnung 11 ein. Zusätzlich werden die beiden Hammerköpfe 22 bei dieser Bewegung in Pfeilrichtung- in die entsprechenden Öffnungen 12 eingebracht, so dass über den Hakenverbinder 21 und die beiden Hammerköpfe 22 das Erweiterungsgehäuse 20 mit dem Basisgehäuse 10 verbunden wird. Zusätzlich kann, wie in Figur 4 dargestellt, das Erwei- teriαngsgehäuse 20 in einem zweiten Montageschritt noch mittels entsprechender Schraubverbindungen 23 fest mit dem Basisgehause verbunden werden. Zum Schluss wird in dem in Figur 5 gezeigten Montageschritt noch ein entsprechender Deckel 30, 30 x auf die Oberseite des Basisgehäuses 10 und des Erwei- terxαngsgehäuses 20 gebracht. Bevorzugt ist dieser Deckel 30,30' einstückig ausgebildet, um möglichst wenig Bauteile zu verwenden. Um eine Flexibilität in der Erweiterung zu gewährleisten, würde bei einer einstückigen Ausbildung aber eine hohe Lagerhaltung für die verschiedenen Erweiterungsmöglichkeiten notwendig sein, so dass es sinnvoll ist, entsprechende Basisdeckel 30 vorzusehen, an die auf einfachste Weise Erwei- ter-ungsdeckel 30 λ angebracht werden können.The individual assembly steps of the expansion housing 20 on the base housing 10 are shown in FIGS. 3-5. Thus, in the first step shown in FIG. 3, the housing extension 20 is connected to the base housing 10 by moving the housing extension on the side wall of the base housing 10 in the direction of the arrow. For this purpose, however, the hook connection 21 must first be introduced into the corresponding opening 11 in the side wall 10 ′ of the base housing 10. When the housing extension 20 is pressed down in the direction of the arrow, the hook connection 21 then hooks into the opening 11. In addition, the two hammer heads 22 are introduced into the corresponding openings 12 during this movement in the direction of the arrow, so that the extension housing 20 is connected to the base housing 10 via the hook connector 21 and the two hammer heads 22. In addition, as shown in FIG. 4, the expansion housing 20 can also be firmly connected to the base housing in a second assembly step by means of corresponding screw connections 23. Finally, in the assembly step shown in FIG. 5, a corresponding cover 30, 30 × is placed on the top of the base housing 10 and the expansion housing 20. This cover 30, 30 'is preferably formed in one piece in order to use as few components as possible. To ensure flexibility in the expansion, but would a high storage for the various expansion options be necessary in a one-piece design, so it makes sense to provide corresponding base cover 30 are attached to the ter-ungsdeckel simple way expanded 30 λ can.

Durch das erfindungsgemäße Gehäuse ergabt sich die Möglichkeit mit geringstem Aufwand, dass heißt mit möglichst wenig Bauteilen, adaptiv das Gehäuse einer Motorsteuerung an deren Leistungsbedarf anzupassen. Selbstverständlich kann die zuvor beschriebene Erfindung auch dadurch realisiert werden, dass ein entsprechendes Erweite- rungsgehäuse an einer anderen Seitenwand oder auch am Deckel des Basisgehäuses angebracht werden kann, um bei erhöhtem Leistungsbedarf entsprechende Bauelemente, wie beispielsweise die Steuerelektronik, aufzunehmen. Andererseits kann das er- findxxngsgemäße Gehäuse auch dadurch realisiert werden, dass an mehreren Seitenteilen des Basisgehäuses Erweiterungsgehäuse angebracht werden. Letztendlich ist die Art der Erweiterung; nämlich bestimmt, durch den zur Verfügung stehenden Platz um den Motorstarter. Wichtig ist bei allen Ausführungen, dass das Erweiterungsgehäuse stabil mit dem Basisgehäuse verbunden ist. Dazu sind wie in dem zuvor beschriebenen Ausführungsbeispiel am Erweiterungsgehäuse entsprechende Rasthaken und Hammerköpfe an verschiedenen versetzten Punkten des Erweiterungsgehäuses vorgesehen, die mit den entsprechenden Öffnungen im Basisgehäuse eine feste Verbindung zwischen bei- den Gehäuseteilen ermöglichen. Andere Befestigungsmittel, wie beispielsweise eine Vielzahl von Rasthaken im Basisgehäuse und entsprechende Öffnungen im Erweiterungsgehäuse, sind genauso denkbar, solange die Flexibilität in der Art der Gehäuseerweiterung und die Sicherheit in der Verbindung dieser Ge- häuseerweiterung gewährleistet ist. The present invention has been shown on the basis of a possible exemplary embodiment. With the housing according to the invention, there is the possibility with minimal effort that means with as few components as possible to adaptively adapt the housing of an engine control system to its power requirements. Of course, the invention described above can also be implemented in that a corresponding extension housing can be attached to another side wall or also to the cover of the base housing in order to accommodate corresponding components, such as the control electronics, when the power requirement is increased. On the other hand, the housing according to the invention can also be realized in that extension housings are attached to several side parts of the basic housing. Ultimately, the type of expansion; namely determined by the space available around the motor starter. It is important for all versions that the expansion housing is stably connected to the basic housing. For this purpose, as in the previously described exemplary embodiment, corresponding latching hooks and hammer heads are provided on the offset housing of the expansion housing, which, with the corresponding openings in the base housing, enable a firm connection between the two housing parts. Other fastening means, such as, for example, a large number of latching hooks in the base housing and corresponding openings in the extension housing, are also conceivable, as long as the flexibility in the type of housing extension and the security in the connection of this housing extension is guaranteed.
